  • Converting HLS Stream to stream supported by old radio

    29 novembre 2024, par Alberto Faenza

    I have an old internet radio that does not support HLS streams.
Therefore I cannot listen to my favourite radio at this url :
https://streamcdnf31-4c4b867c89244861ac216426883d1ad0.msvdn.net/radiodeejay/radiodeejay/master_ma.m3u8

    


    I found a solution using a paid software https://minimradio.com/ which is based on minimserver and minimstreamer.

    


    This solution works if I install mininmserver and minimstreamer on a local computer and use the internet radio to point to the converter stream but I will have to pay if I want to use this.

    


    Checking the documentation of minimradio and ministreamer I can see the following :

    


    *Some internet radios can play the previous AAC ADTS streams but can't play these new HLS streams
...

    


    If the network stream URL points to an HLS .m3u8 master playlist or media playlist file, MinimStreamer reads this file and uses the HLS protocol to read the stream audio data and send it to the music player as a conventional HTTP stream. This makes the stream playable on music players that don't support the HLS protocol. The audio data in the stream must be encoded in AAC format.*
and not a single destination receiver I should use a streaming (broadcasting) server. What can I use to do that ?

    


    My question is the following :
Is there a way to replicate what minimstreamer is doing using ffmpeg ?
I have tried this :

    


    


    ffmpeg -re -i https://streamcdnf31-4c4b867c89244861ac216426883d1ad0.msvdn.net/radiodeejay/radiodeejay/master_ma.m3u8 -c copy -listen 1 -f mpegts http://192.168.1.9:10000

    


    


    which is playing corrctly in local vlc on the same computer. But when I stop VLC is got this error in ffmpeg :

    What is the correct way to stream this one locally in order to be listened in my internet radio ?
Shall I use ffmpeg or can be done directly with ngnix ? Or shall I use both ?

    


  • FFmpeg wrong codecstring for DASH manifest [closed]

    21 novembre 2024, par Suxsem

    I'm trying to create a DASH stream with ffmpeg with the following command :

    


    ffmpeg -i rtsp://admin:***@camera-retro.lan/ch0_0 ^
       -map 0 ^
       -codec:v copy ^
       -codec:a copy ^
       -f dash ^
       -use_template 1 ^
       -use_timeline 1 ^
       -window_size 50 ^
       -extra_window_size 5 ^
       -seg_duration 5 ^
       tmp/output.mpd


    


    The problem is the generated manifest doesn't contain a valid codecstring for the video part (note the codecs="hev1" part) and thus is not playable by the browser :

    


    &lt;?xml version="1.0" encoding="utf-8"?>&#xA;<mpd xmlns="urn:mpeg:dash:schema:mpd:2011" profiles="urn:mpeg:dash:profile:isoff-live:2011" type="dynamic" minimumupdateperiod="PT6S" suggestedpresentationdelay="PT6S" availabilitystarttime="2024-11-21T12:05:52.604Z" publishtime="2024-11-21T12:05:57.559Z" timeshiftbufferdepth="PT5M1.9S" maxsegmentduration="PT5.0S" minbuffertime="PT12.0S">&#xA;    <programinformation>&#xA;        &#xA;    </programinformation>&#xA;    <servicedescription>&#xA;    </servicedescription>&#xA;    <period start="PT0.0S">&#xA;        <adaptationset contenttype="video" startwithsap="1" segmentalignment="true" bitstreamswitching="true" maxwidth="2304" maxheight="1296" par="16:9">&#xA;            <representation mimetype="video/mp4" codecs="hev1" bandwidth="822093" width="2304" height="1296" scantype="unknown" sar="1:1">&#xA;                <segmenttemplate timescale="90000" initialization="init-stream$RepresentationID$.m4s" media="chunk-stream$RepresentationID$-$Number%05d$.m4s" startnumber="1">&#xA;                    <segmenttimeline>&#xA;                        <s t="0" d="542990"></s>&#xA;                    </segmenttimeline>&#xA;                </segmenttemplate>&#xA;            </representation>&#xA;        </adaptationset>&#xA;        <adaptationset contenttype="audio" startwithsap="1" segmentalignment="true" bitstreamswitching="true">&#xA;            <representation mimetype="audio/mp4" codecs="mp4a.40.2" bandwidth="34143" audiosamplingrate="16000">&#xA;                <audiochannelconfiguration schemeiduri="urn:mpeg:dash:23003:3:audio_channel_configuration:2011" value="1"></audiochannelconfiguration>&#xA;                <segmenttemplate timescale="16000" initialization="init-stream$RepresentationID$.m4s" media="chunk-stream$RepresentationID$-$Number%05d$.m4s" startnumber="1">&#xA;                    <segmenttimeline>&#xA;                        <s t="0" d="81001"></s>&#xA;                    </segmenttimeline>&#xA;                </segmenttemplate>&#xA;            </representation>&#xA;        </adaptationset>&#xA;    </period>&#xA;</mpd>&#xA;

    &#xA;

    This is the output of ffprobe :

    &#xA;

    SDP:&#xA;v=0&#xA;o=- 1732188474342789 1 IN IP4 192.168.12.162&#xA;s=Session streamed by "rRTSPServer"&#xA;i=ch0_0.h264&#xA;t=0 0&#xA;a=tool:LIVE555 Streaming Media v2023.01.19&#xA;a=type:broadcast&#xA;a=control:*&#xA;a=range:npt=now-&#xA;a=x-qt-text-nam:Session streamed by "rRTSPServer"&#xA;a=x-qt-text-inf:ch0_0.h264&#xA;m=video 0 RTP/AVP 96&#xA;c=IN IP4 0.0.0.0&#xA;b=AS:700&#xA;a=rtpmap:96 H265/90000&#xA;a=fmtp:96 profile-space=0;profile-id=1;tier-flag=0;level-id=186;interop-constraints=000000000000;sprop-vps=QAEMAf//AWAAAAMAAAMAAAMAAAMAuqwJ;sprop-sps=QgEBAWAAAAMAAAMAAAMAAAMAuqABICAFEf5a7kSIi/Lc1AQEBAI=;sprop-pps=RAHA8oSJAzJA&#xA;a=control:track1&#xA;m=audio 0 RTP/AVP 97&#xA;c=IN IP4 0.0.0.0&#xA;b=AS:32&#xA;a=rtpmap:97 MPEG4-GENERIC/16000&#xA;a=fmtp:97 streamtype=5;profile-level-id=1;mode=AAC-hbr;sizelength=13;indexlength=3;indexdeltalength=3;config=1408&#xA;a=control:track2&#xA;

    &#xA;

    it seems to me that all codec informations are present :

    &#xA;

    a=fmtp:96 profile-space=0;profile-id=1;tier-flag=0;level-id=186;interop-constraints=000000000000;&#xA;

    &#xA;

    why ffmpeg is putting only codecs="hev1" instead of the full codecstring (containing the profile, the level and the constraints) ?

    &#xA;

    Thank you

  • How to compress videos on AMD RX 7900 XTX with ffmpeg ? [closed]

    19 novembre 2024, par cprn

    On Nvidia's GTX 1070 I used to do the below command, and it'd produce a way smaller file (often less than half of the original) without any visible degradation (at least for my eyes) :

    &#xA;

    ffmpeg -hwaccel cuda -i file.mp4 -c:v hevc_nvenc -crf 20 file.small.mp4&#xA;

    &#xA;

    Now I switched to AMD's RX 7900 XTX and this command obviously doesn't work.

    &#xA;

    What's the "equivalent" of that command ? As in : getting way smaller file with seemingly no quality loss.

    &#xA;

    What I tried :

    &#xA;

      &#xA;
    1. av1_nvenc ends up in errors :

      2. &#xA;

    &#xA;

    ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i file.mp4 -c:v av1_nvenc file.small.mp4&#xA;

    &#xA;

    Impossible to convert between the formats supported by the filter &#x27;Parsed_null_0&#x27; and the filter &#x27;auto_scale_0&#x27;&#xA;[vf#0:0 @ 0x60f7c1aa7d80] Error reinitializing filters!&#xA;[vf#0:0 @ 0x60f7c1aa7d80] Task finished with error code: -38 (Function not implemented)&#xA;[vf#0:0 @ 0x60f7c1aa7d80] Terminating thread with return code -38 (Function not implemented)&#xA;[vost#0:0/av1_nvenc @ 0x60f7c1b10040] Could not open encoder before EOF&#xA;[vost#0:0/av1_nvenc @ 0x60f7c1b10040] Task finished with error code: -22 (Invalid argument)&#xA;[vost#0:0/av1_nvenc @ 0x60f7c1b10040] Terminating thread with return code -22 (Invalid argument)&#xA;[out#0/mp4 @ 0x60f7c1b0d680] Nothing was written into output file, because at least one of its streams received no packets.&#xA;

    &#xA;

      &#xA;
    1. hevc_vaapi goes through the encoding, but produces 20% bigger files instead of smaller :

      2. &#xA;

    &#xA;

    ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i file.mp4 -c:v hevc_vaapi file.small.mp4&#xA;

    &#xA;

    No idea what I'm doing. I know next to nothing about video encoding, just what I read in the documentation, and I'm stuck. Also, I'm on Linux, but this shouldn't matter, I think.
